[0001] This application is based on and claims the priority of Chinese patent application No. 202210296784.1 filed on March 24, 2022, the disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

[0002] The present disclosure relates to the field of communications technologies, in particular to an information configuration method and apparatus, a storage medium, and a program product.

BACKGROUND

[0003] In current passive optical networks (PONs), low-density parity-check (LDPC) codes are used as forward error correction (FEC), that is, the FEC is obtained from an IEEE mother code by deleting the last one and a half columns of the LDPC code.

[0004] In a related technology, due to different characteristics of various optical distribution networks (ODNs) and different FEC decoding schemes supported by different optical line terminals (OLTs), different optical network units (ONUs) need to use different FEC codes to adapt to performance of different ONUs. However, there is currently no relevant solution that can enable different ONUs to adaptively use different FEC codes.

SUMMARY

DETAILED DESCRIPTION

[0015] In order to make the objectives, technical schemes and advantages of the present disclosure more apparent, the present disclosure is further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the particular embodiments described herein are only intended to explain the present disclosure and are not intended to limit the present disclosure.

[0016] It is to be noted that although a logical order is shown in the flowcharts, the steps shown or described may be performed, in some cases, in a different order from the order shown or described in the flowcharts. The terms such as "first" and "second" in the description, claims and above-mentioned drawings are intended to distinguish between similar objects and are not necessarily to describe a specific order or sequence.

[0017] The present disclosure provides an information configuration method, an information configuration apparatus, a computer-readable storage medium, and a computer program product. The information configuration method of an embodiment includes: determining target ECC information according to a candidate ECC type supported by an OLT; and sending the target ECC information to an ONU, such that by using the target ECC information, the ONU performs ECC encoding on communication data sent to the OLT. In this embodiment, the target ECC information is first determined according to the candidate ECC type supported by the OLT, and then the target ECC information is sent to the ONU, such that by using the target ECC information, the ONU performs ECC encoding on the communication data sent to the OLT. The target ECC information is selected by the OLT according to an actual network condition, for example, target ECC information matching the ONU can be selected. Therefore, when the ONU uses the target ECC information to perform ECC encoding on the communication data sent to the OLT, the ONU adaptively uses a corresponding ECC for encoding. This fills the technical gap in an existing method.

[0018] The embodiments of the present disclosure will be further explained below with reference to the accompanying drawings.

[0019] FIG. 1 is a flowchart of an information configuration method according to an embodiment of the present disclosure. The information configuration method is applied to an OLT.

[0020] In the example shown in FIG. 1, the information configuration method includes, but is not limited to, steps S110 and S120.

[0021] At S110, target ECC information is determined according to a candidate ECC type supported by the OLT.

[0022] It can be understood that different OLTs support different FEC decoding schemes and support different quantities of FEC decoding schemes. Different ONUs need to use different FEC code types to adapt to performance of different ONUs.

[0023] It should be noted that there may be one or more pieces of target ECC information. In the case of a plurality of pieces of target ECC information, the ONU can subsequently perform selection or replacement.

[0024] At S120, the target ECC information is sent to the ONU, such that by using the target ECC information, the ONU performs ECC encoding on communication data sent to the OLT.

[0025] Referring to FIG. 2, in a possible implementation, in an initial online phase of the ONU, step S110 is further explained. Step S110 may include but is not limited to steps S210 and S220.

[0026] At S210, an initial ECC type is selected from candidate ECC types supported by the OLT.

[0027] Generally, in the initial online phase of the ONU, from the candidate ECC types supported by the OLT, one with the strongest error correction ability is selected as the initial ECC type, or one suitable for error correction by the OLT is selected as the initial ECC type.

[0028] At S220, the initial ECC type is determined as the target ECC information.

[0029] In a possible implementation, the target ECC information includes a target ECC type. Referring to FIG. 3, FIG. 3 is a further supplement to the information configuration method on the basis of FIG. 1, and the information configuration method further includes steps S130, S140, and S150.

[0030] At S130, operation parameter information of an ODN is obtained.

[0031] At S140, the target ECC type is replaced according to the operation parameter information of the ODN.

[0032] At S150, a replaced target ECC type is sent to the ONU, such that by using the replaced target ECC type, the ONU performs ECC encoding on communication data sent to the OLT.

[0033] It can be understood that the ODN sends the collected operation parameter information to the OLT, such that the OLT can replace the target ECC type according to a current communication condition so that the ONU uses a more suitable target ECC type to perform ECC encoding.

[0034] Referring to FIG. 4, in a possible implementation, step S110 is further explained. Step S110 may include but is not limited to steps S410 to S440.

[0035] At S410, error correction encoding information sent by the ONU is obtained.

[0036] At S420, the error correction encoding information is decoded to obtain error correction decoding information.

[0037] At S430, a current bit error rate (BER) is calculated according to the error correction encoding information and the error correction decoding information.

[0038] At S440, the target ECC information is determined according to the current BER and the candidate ECC type supported by the OLT.

[0039] It can be understood that, when the ONU is initially online, a high Margin parameter can be used for registration. In this case, a FEC code has a strong error correction ability. If a decoding flag of the FEC code indicates successful decoding after registration, the error correction encoding information sent by the ONU is obtained. The error correction encoding information is decoded to obtain the error correction decoding information. Then, the current BER is calculated according to the error correction encoding information and the error correction decoding information. Finally, according to the current BER, the target ECC information matching the current BER is determined from candidate ECC types supported by the OLT.

[0040] It can be understood that, when the ONU is initially online, a candidate ECC type suitable for error correction by the OLT can also be selected as the initial ECC type, for example, another FEC code with an error correction ability can be used, provided that the OLT can perform error correction.

[0041] Additionally, it is to be noted that, in some embodiments, before the sending the target ECC information to an ONU, the information configuration method further includes: sharing the candidate ECC type with the ONU.

[0042] The OLT first shares the supported candidate ECC type with the ONU, such that after the OLT sends the target ECC information to the ONU, the ONU can normally use the target ECC information to perform ECC encoding, so as to avoid a case that the target ECC information sent by the OLT cannot be used by the ONU.

[0043] In a possible implementation, the OLT shares the supported candidate ECC type with the ONU in the following manner:
sending burst profile control information including the candidate ECC type to the ONU, such that the ONU stores the candidate ECC type in the burst profile control information.

[0044] The OLT stores the candidate ECC type in the burst profile control information, and then sends the burst profile control information to the ONU. After receiving the burst profile control information carrying the candidate ECC type, the ONU stores the candidate ECC type to realize sharing of the supported candidate ECC type between the OLT and the ONU.

[0045] It can be understood that the OLT may also share the supported candidate ECC type with the ONU in other manners, for example, the OLT agrees with the ONU on storing the candidate ECC type in common.

[0046] In a possible implementation, the target ECC information includes code type indication information for indicating a target ECC type to be used. The sending the target ECC information to an ONU, such that by using the target ECC information, the ONU performs ECC encoding on communication data sent to the OLT in S120 includes:
sending a bandwidth allocation map including the code type indication information to the ONU, such that the ONU obtains the target ECC information according to the code type indication information, and performs, according to the target ECC information, ECC encoding on the communication data sent to the OLT.

[0047] The OLT stores the code type indication information in the bandwidth allocation map, and then sends the bandwidth allocation map to the ONU. After receiving the bandwidth allocation map carrying the code type indication information, the ONU obtains the target ECC information according to the code type indication information, to perform ECC encoding on the communication data by using the target ECC information.

[0048] In a possible implementation, the target ECC information includes a target ECC type and configuration information for information to be deleted, where the configuration information for information to be deleted is used to indicate a deletion mode of content in an ECC. The sending the target ECC information to an ONU, such that by using the target ECC information, the ONU performs ECC encoding on communication data sent to the OLT in S120 includes:
sending the target ECC type and the configuration information for information to be deleted to the ONU through ECC configuration parameter information, such that by using the target ECC information and the configuration information for information to be deleted, the ONU performs ECC encoding on the communication data sent to the OLT.

[0049] The OLT stores the target ECC type and the configuration information for information to be deleted in the ECC configuration parameter information, and then sends the ECC configuration parameter information to the ONU. After receiving the ECC configuration parameter information, the ONU performs ECC encoding on the communication data by using the target ECC information and the configuration information for information to be deleted.

[0050] In some possible embodiments, the OLT sends the target ECC type and the configuration information for information to be deleted to the ONU through the ECC configuration parameter information until a count of transmissions reaches a first preset number of times, such that the ONU stores the target ECC type and the configuration information for information to be deleted; and sends the bandwidth allocation map to the ONU, such that after completing analysis of the bandwidth allocation map, the ONU performs, according to the target ECC type and the configuration information for information to be deleted, ECC encoding on the communication data sent to the OLT.

[0051] The OLT first sends the ECC configuration parameter information carrying the target ECC type and the configuration information for information to be deleted to the ONU, and the ONU receives and stores the target ECC type and the configuration information for information to be deleted. Then the OLT sends the bandwidth allocation map to the ONU as a trigger, such that after completing analysis of the bandwidth allocation map, the ONU performs, according to the stored target ECC type and the configuration information for information to be deleted, ECC encoding on the communication data sent to the OLT.

[0052] In another possible embodiment, the OLT sends the target ECC type and the configuration information for information to be deleted to the ONU through the ECC configuration parameter information, such that after receiving the ECC configuration parameter information, the ONU uses a new ECC in an uplink bandwidth according to the target ECC type and the configuration information for information to be deleted.

[0053] In some possible embodiments, the target ECC information includes a target ECC type. Referring to FIG. 5, step S120 is further explained. Step S120 may include but is not limited to steps S510 and S520.

[0054] At S 510, ECC configuration parameter information corresponding to the target ECC type is determined.

[0055] At S520, the target ECC type and the ECC configuration parameter information are sent to the ONU, such that by using the target ECC type and the ECC configuration parameter information, the ONU performs ECC encoding on the communication data sent to the OLT.

[0056] It can be understood that the target ECC information includes the target ECC type. After the ECC configuration parameter information is determined according to the target ECC type, the target ECC type and the ECC configuration parameter information are directly sent to the ONU, so that the ONU can directly use the target ECC type and the ECC configuration parameter information to perform ECC encoding.

[0057] In some possible embodiments, the ECC configuration parameter information includes configuration information for information to be deleted and a target superframe sequence number, and the configuration information for information to be deleted is used to indicate a deletion mode of content in an ECC. Referring to FIG. 6, step S520 is further explained. Step S520 may include but is not limited to steps S610 and S620.

[0058] At S610, the target ECC information, the configuration information for information to be deleted, and the target superframe sequence number are sent to the ONU until a count of transmissions reaches a second preset number of times or response information fed back by the ONU is received, such that the ONU stores the target ECC information, the configuration information for information to be deleted, and the target superframe sequence number.

[0059] At S620, a superframe is sent to the ONU, such that after receiving a superframe with the target superframe sequence number, the ONU performs, according to the target ECC information and the configuration information for information to be deleted, ECC encoding on the communication data sent to the OLT.

[0060] It can be understood that, the OLT first sends the target ECC information, the configuration information for information to be deleted, and the target superframe sequence number to the ONU, and the ONU stores these pieces of information upon reception, and feeds back response information to the OLT. In response to not receiving any response information, the OLT sends the target ECC information, the configuration information for information to be deleted, and the target superframe sequence number again until the count of transmissions reaches the second preset number of times. When the target ECC information and the configuration information for information to be deleted are needed for performing ECC encoding, the OLT sends a superframe with the target superframe sequence number to the ONU, thereby triggering the ONU to use the stored target ECC information and the configuration information for information to be deleted.

[0061] In some possible embodiments, the ECC configuration parameter information includes region information of information to be deleted, a target superframe sequence number, delete payload region information, and delete check region information. Referring to FIG. 7, step S520 is further explained. Step S520 may include but is not limited to steps S710 and S720.

[0062] At S710, the target ECC information, the region information of information to be deleted, the target superframe sequence number, the delete payload region information, and the delete check region information are sent to the ONU, such that the ONU stores the target ECC information, the region information of information to be deleted, the target superframe sequence number, the delete payload region information, and the delete check region information.

[0063] At S720, a superframe is sent to the ONU, such that after receiving a superframe with the target superframe sequence number, the ONU performs, according to the target ECC information, the region information of information to be deleted, the delete payload region information, and the delete check region information, ECC encoding on the communication data sent to the OLT.

[0064] It can be understood that, the OLT first sends the target ECC information, the region information of information to be deleted, the target superframe sequence number, the delete payload region information, and the delete check region information to the ONU, and the ONU stores these pieces of information upon reception. When the target ECC information, the region information of information to be deleted, the delete payload region information, and the delete check region information are needed for performing ECC encoding, the OLT sends a superframe with the target superframe sequence number to the ONU, thereby triggering the ONU to use the stored information.

[0065] In some possible embodiments, the target ECC information includes code type indication information, and the ECC configuration parameter information includes use indication information. Step S520 is further explained. Step S520 may include the following step:
sending burst profile information including the code type indication information and the use indication information to the ONU, such that the ONU performs, according to the code type indication information and the use indication information, ECC encoding on the communication data sent to the OLT.

[0066] It can be understood that, in this embodiment, the OLT stores the code type indication information and the use indication information in the burst profile information, which are sent to the ONU together with the burst profile information.

[0067] Additionally, in some possible embodiments, the OLT may further send code type update information to the ONU, such that the ONU modifies the code type indication information according to the code type update information, and performs, according to the use indication information and modified code type indication information, ECC encoding on the communication data sent to the OLT, thereby realizing modification of the target ECC type.

[0068] The information configuration method applied to the OLT will be further explained below with reference to specific embodiments.

Embodiment I:

[0069] Refer to Table 1 below, which presents new "Upstream FEC Code Configuration" Physical Layer Operations, Administration and Maintenance (PLOAM) information added to carry burst profile control information and configuration information for information to be deleted. Here, byte 5 carries the burst profile control information, and bytes 6 to 40 carry the configuration information for information to be deleted. Specifically, in the configuration information for information to be deleted, bytes 7 to 11 constitute a deletion configuration unit. For example, this unit indicates a basic type upon which deletion is based, whether the unit of information deletion is bit-based or column-based, whether an information deletion region is located in a payload region or a check region, a start position of deletion, a length of deletion, and the like. Byte 6 is N, indicating that N deletion configuration units are configured in the PLOAM information. Bytes 12 to 40 contain remaining (N-1) deletion configuration units, each with the same structure as the deletion configuration unit constituted by bytes 7 to 11. If there are any remaining byte in bytes 12 to 40, the remaining byte is padding.

Table 1

Byte sequence number	Content	Description
1-2	ONU-ID	A targeted packet is sent to one specific ONU or a broadcast packet is sent to all ONUs.
		As broadcast to all ONUs, ONU-ID = 0x03FF.
3	0x1F	It is a type field indicating that the information is "Upstream FEC Code Configuration" type information
4	SeqNo	Unicast PLOAM sequence number
5	Burst profile control 1	Its form is eight bytes of VWB BBPP, where:
		VVV-Three bytes of burst profile version. If content of a burst profile changes, OLT CT should ensure that the version also changes so that the ONU checks for update based only on a version field.
		BBB-Code point indicating applicability of a message to a particular uplink rate. The code point is specified in applicable physical medium dependent (PMD) recommendations.
		PP-Two bytes of burst profile field.
6	Number of deletion	N, which represents the number of deletion configuration units constituted by bytes 7 to 11
7	Delete content	RRRRBDDP, where:
		R-Reserved
		B: 0-IEEE mother code, 1-50G-PON LDPC, basic code type
		DD: 00-bit, 01-byte, 10-column, 11-reserved, information deletion unit
		P: 0-payload region, 1-check region, information deletion region
8-9	start position	Start position of deletion
10-11	Length	Length of deletion
12-40	...	(N-1) deletion configuration units are included, each with the same structure as the deletion configuration unit constituted by bytes 7 to 11, and the remaining bytes are padding.
41-48	Message integrity check (MIC)	A MIC value is calculated using a default PLOAM integrity key.

[0070] It should be noted that meanings of the remaining bytes in the PLOAM information are the same as meanings of corresponding bytes in PLOAM information in the prior art, and will not be repeated herein.

[0071] FIG. 8 is a schematic diagram of a bandwidth allocation map (BWmap) with code type indication information. The burst profile field Burst_Profile is used for extension, and the Burst profile control 1 field in Table 1 above is associated with the burst profile field Burst Profile. The burst profile control information in ECC configuration parameter information is selected through the burst profile field Burst Profile in the BWmap. In this way, an uplink FEC code type can continuously be used, or the uplink FEC code type can be switched at any time. The OLT in a deployment phase can determine and continuously use an uplink FEC code type according to a decoding method used by the OLT and evaluation of an ODN. Alternatively, the OLT in the deployment phase may first use a code type with a strong error correction ability, then evaluate, in subsequent operation, a decoding method used by the OLT and the ODN, and based on an evaluation result, replace the current code type with a more suitable uplink FEC code type, for example, a code type with a slightly weaker error correction ability but high bandwidth efficiency. Certainly, the OLT may also evaluate the decoding method and a limit error tolerance ability of the ODN, that is, the error correction ability of the uplink FEC code type is caused to gradually reduce until a FEC decoding flag indicates a failure of decoding. Subsequently, bandwidth efficiency can be adjusted according to an uplink traffic volume. For example, when the uplink traffic volume is large, an uplink FEC code type with higher bandwidth efficiency is used; when the uplink traffic volume is small, an uplink FEC code type with lower bandwidth efficiency is used.

[0072] It should be noted that the code type indication information includes at least one of the following:

bits of a burst profile field in a bandwidth allocation map;

partial bits of a start time field in the bandwidth allocation map; or

partial bits of a grant size field in the bandwidth allocation map.

[0073] In actual deployment, due to factors such as varying lengths of branched optical fibers, different optical splitters, and different surrounding environments at the OLTs, a plurality of FEC code types may be needed to ensure that each OLT operates at an optimal state in terms of error correction capability and bandwidth efficiency. When the code type indication information includes only bits of the burst profile field in the bandwidth allocation map, since the current Burst Profile has only 2 bits, the burst profile field can indicate at most 4 different FEC code types. Therefore, different FEC code types can be classified into four or less classes, and each class uses one FEC code type. In addition, bits of the code type indication information may be expanded. For example, a maximum of 2 bits of the start time field StartTime in the bandwidth allocation map and a maximum of 2 bits of the grant size field GrantSize in the bandwidth allocation map are used. The code type indication information may indicate 16 FEC code types using 4 bits, or may indicate a total of 64 FEC code types using 6 bits.

[0074] It can be understood that when a particular FEC code type needs to be updated, an ONU using this FEC code type can switch to another code type for use, and switch back after the code type is updated.

Embodiment II:

[0075] Refer to Table 2 below, which presents new "Upstream FEC Code Configuration" PLOAM information added to carry configuration information for information to be deleted. Here, bytes 5 to 40 carry the configuration information for information to be deleted. Specifically, in the configuration information for information to be deleted, bytes 6 to 10 constitute a deletion configuration unit. For example, this unit indicates a basic type upon which deletion is based, whether the unit of information deletion is bit-based or column-based, whether an information deletion region is located in a payload region or a check region, a start position of deletion, a length of deletion, and the like. Byte 5 is N, indicating that N deletion configuration units are configured in the PLOAM information. Bytes 11 to 40 contain remaining (N-1) deletion configuration units, each with the same structure as the deletion configuration unit constituted by bytes 6 to 10. If there are any remaining byte in bytes 11 to 40, the remaining byte is padding.

Table 2

Byte sequence number	Content	Description
1-2	ONU-ID	A targeted packet is sent to one specific ONU or a broadcast packet is sent to all ONUs.
		As broadcast to all ONUs, ONU-ID = 0x03FF.
3	0x1F	It is a type field indicating that the information is "Upstream FEC Code Configuration" type information
4	SeqNo	Unicast PLOAM sequence number
5	Number of deletion	N, which represents the number of deletion configuration units constituted by bytes 6 to 10
6	Delete content	RRRRBDDP, where:
		R-Reserved
		B: 0-IEEE mother code, 1-50G-PON LDPC, basic code type
		DD: 00-bit, 01-byte, 10-column, 11-reserved, information deletion unit
		P: 0-payload region, 1-check region, information deletion region
7-8	start position	Start position of deletion
9-10	Length	Length of deletion
11-40	...	(N-1) deletion configuration units are included, each with the same structure as the deletion configuration unit constituted by bytes 6 to 10, and the remaining bytes are padding.
41-48	MIC	A MIC value is calculated using a default PLOAM integrity key.

[0076] It should be noted that meanings of the remaining bytes in the PLOAM information are the same as meanings of corresponding bytes in PLOAM information in the prior art, and will not be repeated herein.

[0077] In an example, a PLOAM message is sent three times before a bandwidth is allocated to a corresponding ONU, and the ONU stores an uplink FEC code type. After that, an OLT allocates a bandwidth to the ONU, and the ONU uses the stored uplink FEC code type to increase a check for an uplink burst. In another example, the PLOAM information and a bandwidth allocation map are allocated in the same downlink superframe. The OLT needs to analyze the bandwidth allocation map and the PLOAM information before sending the uplink burst. If there is an uplink FEC code type in the same downlink superframe, the FEC code type in the message is adopted. In another case, bandwidth allocation before the PLOAM information uses an old FEC code type, while bandwidth allocation after the PLOAM information uses a new FEC code type.

[0078] It can be understood that when a particular FEC code type needs to be updated, an ONU using this FEC code type can switch to another code type for use, and switch back after the code type is updated.

Embodiment III:

[0079] Refer to Table 3 below, which presents new "Upstream FEC Code Configuration" PLOAM information added to carry configuration information for information to be deleted and a target superframe sequence number. Here, bytes 5 to 8 carry the target superframe sequence number, and bytes 9 to 40 carry the configuration information for information to be deleted. Specifically, in the configuration information for information to be deleted, bytes 10 to 14 constitute a deletion configuration unit. For example, this unit indicates a basic type upon which deletion is based, whether the unit of information deletion is bit-based or column-based, whether an information deletion region is located in a payload region or a check region, a start position of deletion, a length of deletion, and the like. Byte 9 is N, indicating that N deletion configuration units are configured in the PLOAM information. Bytes 15 to 40 contain remaining (N-1) deletion configuration units, each with the same structure as the deletion configuration unit constituted by bytes 10 to 14.

[0080] Based on Embodiment II, this embodiment adjusts the definition of the PLOAM message by adding, to the PLOAM information, the target superframe sequence number SFC (Superframe Counter), which instructs the ONU to use a new FEC code type after a superframe with the target superframe sequence number is received. Prior to this, an OLT sends a configured PLOAM message, and the ONU replies with an Acknowledage PLOAM message after receiving the configured PLOAM message. If the OLT does not receive any Acknowledage PLOAM message, the OLT continues to send the configured PLOAM message until a count of transmissions reaches a second preset number of times.

Embodiment IV:

[0081] In an example, a FEC code type may be set through an ONU management and control interface (OMCI) manner, and commencement of effectiveness of the code type can be set to start from a specific superframe. For example, an attribute of Upstream FEC Code Configuration is defined in an OMCI management entity OLT-G, including:

first field: region information of information to be deleted, 1 byte, 0-payload region, 1-check region;

second field: target superframe sequence number, 4 bytes, sequence number of a specified superframe;

third field: delete payload region information, 4 bytes, where a delete start column is 2 bytes, and the number of delete columns is 2 bytes; and

fourth field: delete check region information, 4 bytes, where a delete start column is 2 bytes, and the number of delete columns is 2 bytes.

[0082] It can be understood that when a particular FEC code type needs to be updated, an ONU using this FEC code type can switch to another code type for use, and switch back after the code type is updated.

Embodiment V:

[0083] Refer to Table 4 below, which defines byte 6 in bust profile information Burst_Profile.

Table 4

6	Burst profile control 2	NNMM RRCF, where:
		NN-The total number of PSBu segments minus 1, with a range of 0-3.
		MM-Sequence numbers of consecutive PSBu segments starting from zero, with a range of 0-NN. The PSBu segments transmitted on an optical channel will be concatenated in an order provided by the field, where 0 corresponds to a PSBu segment to be transmitted first.
		C-Cross channel flag for burst profile information (TWDM only); C = 0: The message applies to the channel; C = 1: If it is transmitted in a downstream wavelength channel, it can be identified using a downstream PON ID provided by bytes 35 to 38 of the message.
		F-Upstream FEC indication:
		F = 1: FEC enabled; F = 0: FEC disabled.
		RR = 00: code0
		RR = 01: code1
		RR = 10: code2
		RR = 11: code3
		Contents of NN, C, and F are set to be valid only in the first message corresponding to the burst profile information (that is, when MM = 0).

[0084] It can be understood that in the burst profile information Burst_Profile, except that the two bits of RR in byte 6 are redefined, RR = 00: code0, RR = 01: code1, RR = 10: code2, RR = 11: code3, meanings of other bytes of the burst profile information Burst Profile are consistent with those in other related technologies, and will not be repeated herein.

[0085] In actual deployment of this embodiment, several uplink FEC code types can be set in advance, for example, four code types are defined in advance in the standard, code0: LDPC (C0, P0), code1: LDPC (C1, P1), code2: LDPC (C2, P2), and code3: LDPC (C3, P3). If Burst Profile = 00b, code0 is used; if Burst Profile = 01b, code1 is used; if Burst Profile = 10b, code2 is used; if Burst Profile = 11b, code3 is used. Further, it can be understood that additional bits may be carried in the burst profile information Burst Profile for indicating whether the uplink FEC is enabled or disabled.

[0087] It can be understood that Embodiment V described above defines and solidifies code0, code1, code2, and code3 in the standard. This embodiment is more flexible than Embodiment V. For example, although code0, code1, code2, and code3 are defined in the standard, they are not solidified. Subsequently, by sending the PLOAM information carrying code type update information to the ONU, the code type indication information can be modified, such that the ONU can perform, according to use indication information and modified code type indication information, ECC encoding on communication data sent to an OLT.

[0088] Based on the above-described embodiments of the information configuration method applied to the OLT, various embodiments of an information configuration method applied to an ONU of the present disclosure are presented below.

[0089] FIG. 9 is a flowchart of an information configuration method according to an embodiment of the present disclosure. The information configuration method is applied to an ONU.

[0090] In the example shown in FIG. 9, the information configuration method includes, but is not limited to, steps S910, S920, and S930.

[0091] At S910, operation parameter information is sent to an OLT.

[0092] At S920, target ECC information sent by the OLT is received, where the target ECC information is determined by the OLT according to the operation parameter information and a candidate ECC type supported by the OLT.

[0093] At S930, ECC encoding is performed, by using the target ECC information, on communication data sent to the OLT.

[0094] It can be understood that the ONU sends the operation parameter information to the OLT, such that the OLT determines the target ECC information according to the operation parameter information and the candidate ECC type supported by the OLT; and then the ONU receives the target ECC information sent by the OLT and uses the target ECC information to perform ECC encoding on the communication data sent to the OLT. In this way, the ONU adaptively uses a corresponding ECC for encoding. This fills the technical gap in an existing method.

[0095] In some possible embodiments, the target ECC information includes a target ECC type. Referring to FIG. 10, FIG. 10 is a further supplement to the information configuration method on the basis of FIG. 9, and the information configuration method further includes steps 1010, S 1020, and S 1030.

[0115] The OLT stores the code type indication information in the bandwidth allocation map, and then sends the bandwidth allocation map to the ONU. After receiving the bandwidth allocation map carrying the code type indication information, the ONU obtains the target ECC information according to the code type indication information, to perform ECC encoding on the communication data by using the target ECC information.

[0116] In some possible embodiments, the target ECC information includes a target ECC type and configuration information for information to be deleted, where the configuration information for information to be deleted is used to indicate a deletion mode of content in an ECC.

At S1420, after analysis of the bandwidth allocation map is completed, ECC encoding is performed, according to the target ECC information and the configuration information for information to be deleted, on the communication data sent to the OLT.

[0120] The OLT first sends the ECC configuration parameter information carrying the target ECC type and the configuration information for information to be deleted to the ONU, and the ONU receives and stores the target ECC type and the configuration information for information to be deleted.
